Hey Peter,
thank you for your reply. This makes perfectly sense.

Oh ok, this is new to me because on the laptops with a clickpad using two
fingers (one for click and the other one for pointer movement) is not working
(the cursor doesn't move at all when moving the second finger). Is this
behavior working on libinput out-of-the-box or must be enabled somehow? Just to
understand if we are hitting a bug on our hardware.

Thanks,
